Could power supply be the culprit?

post #1 of 14
Thread Starter 
I built my rig (specs in profile) about 2 yrs ago and it has served me well w/ very few problems, however I came back from a weekend trip last night and turn my computer on and come back in to check my email and strangely its off. I think, well thats strange, crank it up again, go fix me a snack and sure enough...its off again. So now im confused. I turn it on again, watch it as it boots up and loads windows. Everything goes fine....for about 20 seconds. All my icons load and then all of a sudden, its shuts down. So next time i start it up i go into the bios and disable all of the auto shutdowns for hi temps, let it start back up and sure enough, craps out again. I do this a couple more times and finally it stays up.

Now, here i am this morning and it does the same thing, except now i cant keep it running. It just shuts down w/o the least warning may a minute after it starts up. Could it be the power supply? I bought a pretty good one Sunbeam that i thought would last for the life of this computer. Or do you think it might be something different? Ive kinda been out of the computer loop for the past couple of yrs due to the lack of need to upgrade this one ive been happy with so i dont really know where to start. Any input would be greatly appreciated.

Does your BIOS show the voltage readings?

ok, ive got it up and running for about 15 minutes now. Ok, i dont remember much about what the different voltages mean and are for but i will just list them off for you:

VCore= 1.44
DDRV= 2.7
+3.3V= 3.39
+5V= 5.16
+12V= 11.55...i think this is low, but i remember it always being this way even 2 yrs ago
CK804= 1.54
HTV= 1.17
5VSB= 4.97

Those were all that are listed in my AbitEQ, see if you can make heads or tails of that

Can you check the 3.3v,5v and 12v in the BIOS under PC Health Status.
Software readings can be unreliable.
Have you gotten any errors,blue screens or had any other problems? clock?

i will definitely check next time i have to reboot, but now its been running for about 1 1/2 hrs and i dont have the guts to restart it since i need some WoW time right now . But no, i havent had any blue screens or any other problems to speak of, thats kinda why im leaning to power supply. Next time i reboot ill post the numbers.

You should also download the DOS versions of memtest and your HDD's test utility too and run them.
